Storicamente le eruzioni laterali dell’Etna, quelle che producono colate di lava da fessure situate lungo i fianchi del vulcano, sono spesso accompagnate da eventi sismici distruttivi nell’area Etnea. L’impatto concomitante dei due fenomeni sul territorio può essere…

Probabilistic PDC invasion maps for four sets of simulations (N=1000 each run) with different values of collapsing volume and vent positions sampled uniformly within Aso caldera. The other input parameters are derived from expert judgment. Dotted gray circles mark the positions of the five marker sites. Contour lines show the…

Histograms of the interevent time of earthquakes and flank eruptions <4 months, including pie charts of the positive values (dark colors), negative values in [−2.5, 0] days (light colors), and lower than −2.5 days (white). (a, c, e) show the earthquakes with Ix ≥ V–VI EMS; (b, d, f) those with Ix ≥ VII–VIII EMS. (a,…
